IMPROVEMENT GISTRN FILTERS.

ro ,All WHoM 1T MAY ooNorLnN;

Be it known that I, GEORGE W. LAMPSON, of Waterloo,iin the county of Seneca, and'Statc of New York, have invented a new and improved Cistern Filter; and I do hereby declare .that the following is atnll, clear-,end exnct description ofthe same. l

The object of my invention is to construct a rain-.Water lter, and adapt it to the-conductor pipe s'o that the rain unter shall be purified or cleansed beforev it enters the cistern. And the'invention consists in constructing' a vessel, and placing in it pons containing alternate layers of gravel, send, and charcoal, or other snbstznices,v into .which the water shall be discharged from the conductor pipe, and from which it may be discharged-into the eistern.v u

i And to'cnahle others skilled in' the art to make and use my invention, I .will proceed to describeits construction :md operation,.referenc'e being hadto the accompanying drawing-which forms'a part of this speci- 'lhe drawing represents a vertical section of my lter. v t, A is the vessel or outside casing, formed at both ends so as to be attached to conductor pipes. B C D and E are pans or vcssels containing gravel and charcoal, or gravel, charcoal, and send, ns maybe desired.1 Other` clearing substances maybe used'n lieu' of, or in connection with, the above. But it is well known thatchareoal is one of the most valuable purifying and disinfecting substances with which we are acquainted, or Which'have been discovered, and,theret`or'e,-I consider it important to use charcoal in all filters for the purification of Wat-er. There may be more' or less of these layers' or pans, as may be deemed best. vAttached to the uppermost vessel B is a cone, whose apex". is d irectlynnder the centre of the pipe which discharges the waterinto the ilter. This cone is perforated; but theprincipal object' of it is to scatter and direct thevwater toward the outside of the vessel Band the other vessels or pans. This arrangement .facilitates the operation. This concis represented by F, .in the drawing. 4TheV bottoms `of these pans'nre slightly concave, and are perforated, to allow thewater to drop from' one pan to the other, and so Von to the bottom. They are constrncted so that they stand o ne upon the other, as seen in the dran'ing, which arrangement vallows them to be easily removed whenever it is necessary to cleanse the lter. Upon the centre of the bottom of the upper lpan B a stilrod is attached, which rod stands in an' upright position. On the under side of the cone F, attached beneath the apex, is a tube, a, which slips over therod, and in this manner the cone is held in position. The upper portion of the vessel. A is removahle', for purposes of cleansing, tc. I

'Having thus described my invention, what I claim as'new, and desire to secure by Letters Patent, is'- The pans B C D and E 'and cone F, in combination with the vessel A, the whole constructed and arranged substantially as and for the purpose described.
